Patent number: 9215155Abstract: A method for selecting a mode of operation for at least two modems is described. First, a handshake procedure is performed in order to determine a set of possible modes of operation supported by said modems. From said set of possible modes of operation, a set of favorable modes of operation is derived. In case there exist two or more favorable modes of operation, a probing-based selection is performed that comprises evaluating respective performances of said favorable modes of operation. The favorable mode of operation with the best performance is selected as a resultant mode of operation.Type: GrantFiled: April 29, 2013Date of Patent: December 15, 2015Assignee: Broadcom CoporationInventors: Miguel Peeters, Raphael Cassiers, Benoit Christiaens, Ruben Lysens, Olivier Van De Wiel

Patent number: 8363762Abstract: The present invention provides digital subscriber line noise mitigation techniques, and applications thereof. In an embodiment, the present invention provides a toolbox of methods and techniques for mitigating the effects of noise in xDSL systems. These methods and techniques are controllable and locatable at one or both ends of a DSL communication link (e.g., within a central office transceiver unit or a remote transceiver unit). These novel methods and techniques include: (1) per tone noise margin modification, (2) data framer constraints modification, (3) improved noise measurements; (4) more robust on-line reconfiguration processes, (5) worst case noise monitoring, (6) induced bit rate limitations, and (7) distortion noise mitigation. These methods and techniques are particularly useful for mitigating the effects of time-varying noise and impulse noise.Type: GrantFiled: May 9, 2011Date of Patent: January 29, 2013Assignee: Broadcom CorporationInventors: Olivier Van de Wiel, Koen Vanbleu, Jean Boxho, Miguel Peeters

Patent number: 6400781Abstract: In a multiband detector (DET), sub-band reconstruction and distortion compensation is performed by a plurality of digital filters (FIR1, . . . , FIRk, . . . , FIRN) arranged in a single-input-multiple-output architecture. Each digital filter (FIRk) is coupled between one and the same input (RDA-I) whereto a distorted multiband signal (si) is applied and a respective output (RDA-Ok) whereto a reconstructed sub-band signal (sik) is applied. This multiband detector (DET) has a uniform architecture for each input-output path and can easily be adapted to changes in distortion of the multiband signal (si), even if these changes only affect a few sub-bands.Type: GrantFiled: October 26, 1998Date of Patent: June 4, 2002Assignee: AlcatelInventors: Luc Andre Marie Vandendorpe, Olivier van de Wiel

Publication number: 20020054610Abstract: In a multicarrier transmission system, a transmitter (T, T′) sends digital data packets (D) modulated on a set of carriers to a receiver (R, R′). A subset of the carriers constituting the set of carriers has frequencies (f1, f2, f3, f4) in predetermined frequency ranges (Amateur Radio Band) with high risk for being affected by narrowbanded interference (RFI), e.g. originating from radio amateur transmission. The data bits of the digital data packets (D) that are allocated to the subset of carriers having frequencies (f1, f2, f3, f4) within these predetermined frequency ranges (Amateur Radio Band), are allocated thereto in a redundant way. Via an allocation message (AM) communicated between the transmitter (T, T′) and the receiver (R, R′) both are aware of the redundancy in the bit allocations.Type: ApplicationFiled: December 11, 2001Publication date: May 9, 2002Inventors: Peter Paul Frans Reusens, Olivier Van De Wiel
